Good Product
by Chris from Welland, Ontario on May 26, 2015
Solid after market products, hasn't leaked....yet! It's hard finding parts for old water craft. I'm sure I'll be back shopping

Q:
I am looking for the piston valve kit for cylinder # 45520 and the stern drive model is a OD458840?
A:
According to your serial number that is not the number for the trim cylinder for your application. The 45520 is obsolete. What is called for your application though is part number 18-2428.


Q:
Will this kit fit trim cylinder with 1" diameter piston and 2.5" diameter cap?
A:
Sierra confirms we need to know the engine information. If you have a Mercury application we need to know serial number in order to match up repair kit.
